First set of closures are due to take place between February 21 and 24

Drivers have been warned to expect delays on a major motorway in the upcoming few weeks as improvement works get underway.

The works will take place on the M25 as National Highways works to upgrade the highly anticipated changes to junction 10 of the motorway.


The scheme will require a set of road closures to take place as the agency removes and demolishes several bridges in the junction.

The closures will take place between 9pm on March 7 until 6am on March 10 and again between 9pm on March 21 till 6am on March 24.

Other works in the coming weeks and months will see the slip roads from Junction 10 closed between February 21 and 24.

Meanwhile, the A3 will be closed in both directions between Junction 10 and Cobham Roundabout/A245 between April 11 and 14.

While the road closures are in place drivers have been urged to plan their journeys well in advance and ensure they allow extra time or make alternative travel arrangements.

Jonathan Wade, National Highways Senior Project Manager, said: "This is the final block of closures on the M25 as this scheme nears completion.

"We were grateful to drivers who listened to our advice during the three weekend closures last year and I’d again urge them to only use the motorway if their journey is absolutely necessary."

He added: "Unfortunately, it’s simply not possible to carry out this scale of infrastructure improvement, which will benefit millions of people in the long term, without there being some degree of short-term disruption.

"We have spent months planning these closures, but they will still cause significant congestion and delays, so we are asking road users to allow extra time and use alternative routes where possible. Please follow our official diversion routes and not information from satnavs."

The Junction 10 improvement scheme will see an increase in the number of lanes to make journeys safer and improve traffic flow.

It will also aim to make it "easier and safer" to enter and exit the M25, provide safer entry roads for Wisley, Pyrford, Old Byfleet and the RHS Garden Wisley as well as work on reducing pollution caused by traffic jams.

Diversion routes for each of these closures will be announced and published closer to each weekend with drivers urged to follow to avoid additional delays.

Wade added that extreme weather last year delayed some elements of work, forcing the final completion date to be moved back to 2026.

"We are already seeing some of the benefits of this project, which will help reduce congestion, create a smoother flow of traffic and provide safer journeys for thousands every day," he stated.

The project was originally started in 2022 with National Highways working on adding extra lanes around Junction 10, where the motorway meets the A3.

Once the roads have opened the benefits of this scheme hope to improve safety and journey times, reduce congestion, smooth the flow of traffic, increase capacity and provide better connections for drivers while improving access for cyclists, pedestrians and horse-riders.
